Ajax，json url只是特定的数据

Question

I'm using this function

var url = 'XXXXXXXX'
        $.ajax({
            type: 'GET',
            dataType: "json",
          //  data: {Calling:Calling},
            processData: false,
            crossDomain: true,
            jsonp: false,
            url: url,
    success: displayAll
});
        function displayAll(r,data){
            for( i in r.Events )
                {           
                    var eventType    = r.Events[i].Event
                    var eventData    = r.Events[i].Data
                    var eventDetails = r.Events[i].Details
                    var caller = r.Events[i].Data.Calling

                    var test = JSON.stringify(caller);
                    console.log(test);
  }

The json XXX URL returns something like

 >Data: {
 >    Billing: "0033912312312" (OVH number)
 >    Body: "SIP/2.0 200 OK" (Header SIP packet)

I need to get the value of Calling and Called to re use it in sql query.

i've tried using

    data: {Calling:Calling, Called:Called},

in the ajax function but since im getting the result from url console returns

 ReferenceError: Calling is not defined

is there a way to pass it to php with data: ? or maybe an alternative (twig?)

---

EDIT : here is what i've tried

   var url = 'xx'

        $.ajax({
            type: 'GET',
            dataType: "json",
            //data: {Calling:Calling},
            processData: false,
            crossDomain: true,
            jsonp: false,
            url: url,
    success: displayAll


});

        function displayAll(r,data){
            for( i in r.Events )
                {
                    // Sotre in last events
                    var eventType    = r.Events[i].Event
                    var eventData    = r.Events[i].Data
                    var eventDetails = r.Events[i].Details
                    var caller = r.Events[i].Data.Calling

                    var test = JSON.stringify(caller);
                    console.log(test);
                    console.log(this);
                    var json = JSON.parse(test);
       $.ajax(
{
    url: 'test.php',
    type:'POST',  
    data: {caller:json},
    success: function(data)
    {
        console.log("ok");
        console.log(json);
    },
    error: function(data)
    {
      console.log("bug");
    }

});
 }

the console.log(json) works console returns :

ok
0033912312312

in the test.php file i've tried :

<?php
 $moui = $_POST['caller'];
 echo $moui;
 var_dump($moui);
 ?>

var dump return null

You need to convert the string json to an object

var json = JSON.parse(data);
//Now access it like so
json['Calling'];
//or
json.Calling;
